  • a spun yam winding device includes a traverse device with traverse guides that reciprocate in an axial direction of winding bobbins. And a contact roller which is contacted with packages is provided on a lower side of the traverse device.

Therefore, with no need of providing a movable portion projecting to the vertical direction of the spun yam winding device 100, it is possible to reduce the size of the spun yam winding device 100 in a vertical direction. As such, the spun yam winding device 100 can be compact.
  • Embodiment 2 differs significantly from Embodiment 1 in that the spun yam winding device 100 according to Embodiment 2 corresponds to the spun yarn winding device 100 according to Embodiment 1 in which a bulge suppressing mechanism and a saddle bag shape collapsing mechanism are additionally provided. A detailed description of the same components as those of Embodiment 1 is omitted.
  • the bulge suppressing mechanism of the spun yam winding device 100 Because yam passages of elastic threads tends to be unstable as the winding speed of the yarns increases, high tension is applied to the elastic threads, and then, the elastic threads are wound onto winding bobbins in an extending condition. When the yarns are wound onto the winding bobbins in the extending condition, tensile stress of the yarns accumulates in the inner portion of packages. Since tightening forces of the yarns due to the accumulation of the tensile stress is enormously powerful, a bulge winding phenomenon and fixation between yarns tend to occur.
  • the bulge winding phenomenon is a phenomenon in which sides of the packages become bulged in convex projection due to the tightening forces of the wound yarns, and thereby the appearance of the package form becomes worse.
  • the rotational speed of the feeding roller 22 is a speed at which the yarns Y are fed to the winding bobbins B which is faster than the speed at which the yarns Y are wound onto the winding bobbins B.
  • the speed at which the feeding roller 22 feeds the yarns Y is determined by a characteristic etc. of the yarns Y.
  • the speed at which the feeding roller 22 feeds the yarns Y is preferably 1.1 or more times of the speed at which the yarns Y are wound onto the winding bobbins B.
  • the saddle bag shape collapsing mechanism of the present embodiment controls the first free length FL1 of the yarns Y which is located between the feeding roller 22 and the winding bobbins B during the package forming period P so as to solve the saddle bag shape phenomenon of the packages 64.
  • the basic operation and changing operation are repeated during the package forming period P by controlling the rotational angle of the turret 16.
  • the first free length FL1 which is located between the feeding roller 22 and the winding bobbins B, of the yarns Y is maintained at the standard length FL11. Meanwhile, during the changing operation, the first free length FL1 is temporarily increased larger than the standard length FL11.
  • a program that performs the control is stored in the ROM of the control unit 14 and executed after loading the program into the RAM.
  • a period during which the basic operation for maintaining the first free length FL1 at the standard length FL11 is performed is defined as a period F1
  • a period during which the changing operation for temporarily increasing the first free length FL1 larger than the standard length FL11 is performed is defined as a period F2 (Refer to Figure 6 ).
  • the period during which the basic operation is performed is defined as the period F1.
  • the first free length FL1 is maintained at the standard length FL11.
  • the packages 64 is gradually increased in winding diameter as the formation of the packages 64 proceeds.
  • the specific control of the basic operation during which the first free length FL1 is maintained at the standard length FL11 corresponding to the increase in winding radius of the packages 64 is the same as that of Embodiment 1. Then, a detailed explanation is omitted.
  • the turret 16 is temporarily rotated largely compared to that of in the state of the basic operation so as to temporarily increase the first free length F1. Therefore, the distance between the shaft center of the feeding roller 22 and the shaft center of the winding bobbins B is enlarged compared to that of in the basic operation.
  • the first free length FL1 is temporarily enlarged up to FL12, which is longer than the standard length FL11.
  • the turret 16 After enlarging the first free length FL1 up to FL12 which is larger than the standard length FL11, the turret 16 is then rotated backward so as to return the rotational angle of the turret 16 to the state of the basic operation. As such, the first free length FL1 returns back to the standard length FL11, and then, the changing operation is terminated.
  • the contact roller 43 is kept in contact with the winding bobbins B under the predetermined contact pressure following the change of the position of the winding bobbins B caused by the changing operation.
  • this changing operation is a control for enlarging the distance between an axial position of the yarns Y in the feeding roller 22 and an axial position where the yarns Y are wound onto the winding bobbins B. That is to say, a traverse delay D1 is temporarily increased up to a traverse delay D2. That is to say, when the first free length FL1 is equivalent to FL11, the yarns Y are wound onto the winding bobbins B at an axial position N1, and the traverse delay at this time is D1. Meanwhile, when the turret 16 is rotated and the first free length FL1 is equivalent to FL12, the yarns Y are wound onto the winding bobbins B at an axial position N2, and the traverse delay at this time is D2.
  • the basic operation and the changing operation are repeated during the package forming period P.
  • the winding during the period F1 of the basic operation allows the yarns Y to be wound to ends of the winding bobbins B
  • the winding during the period F2 of the changing operation reduces the winding width to allow the yarns Y to be wound around the winding bobbins B at a position closer to the axial center thereof.
  • the feeding roller 22 and the traverse device 32 are fixed in position relative to the machine body 12. And conventionally, the turret 16 is structured to rotate relative to the machine body 12. Therefore, the feeding roller 22 and the traverse device 32 are considered as simple and highly reliable structure, and simultaneously, the saddle bag shape phenomenon of the packages 64 can be solved. Also, the bulge winding phenomenon of the packages 64 can simultaneously be solved since the feeding roller 22 feeds the yarns to the winding bobbins B at a speed faster than the winding speed at which the yarns Y are wound onto the winding bobbins B.
  • the spun yarn winding facility 200 of the present embodiment is composed of the combination of the plurality of spun yam winding devices 100 which are described in Embodiment 1 wherein some of which are located on an upper stage and others of which are located on a lower stage. Detailed explanation with regard to the spun yarn winding device 100 is omitted.
  • the spun yam winding devices 100 are located on both the upper and lower stages in a state of longitudinal layout.
  • the yarns Y are spun at a spinning device (not shown in Figures) which is disposed at an upper portion and then fed to each spun yam winding device 100 through the intermediary of the roller 52, and the rollers 54, 56 etc.
  • the yarns Y are fed to the traverse devices 32 of each spun yam winding devices 100 from the upper portion to the lower portion.
  • the spun yam winding facility 200 is composed of the combination of the plurality of spun yam winding devices 100 wherein the spun yarn winding devices 100 are located both the upper and lower stages in a state of longitudinal layout, it is necessary to prevent interference between the yarns Y fed to the spun yam winding devices located on the lower stage and the spun yam winding devices located on the upper stage.
  • the spun yam winding facility 200 of the present embodiment in order to prevent the interference of the yarns Y, the spun yam winding devices 100 located on the lower stage and the spun yam winding devices 100 located on the upper stage are arranged in a zigzag as seen from the side.
  • each yam Y fed to the spun yam winding devices 100 which are located on the lower stage passes between the plurality of spun yam winding devices 100 which are located on the upper stage, and then fed to the traverse devices 32 from an upper portion.
  • the spun yam winding facility 200 is composed of the combination of the plurality of spun yam winding devices 100 wherein the spun yam winding devices 100 are located on both the upper and lower stages in a state of a longitudinal layout, and the spun yam winding facility 200 is configured so that the yarns Y are fed to each of the traverse devices 32 of the spun yam winding devices 100 from the upper portion, the height of the spun yarn winding facility 200 becomes higher, and the excess height causes the problem of the increase in size of the spun yarn winding facility 200. And when the height of the spun yam winding facility 200 becomes higher, particularly the workability for the spun yam winding devices 100 which are located on the upper stage is impaired. For this reason, conventionally, locating the spun yarn winding devices 100 on both the upper and lower stages in a state of a longitudinal layout is difficult to adopt.
  • the spun yam winding devices 100 which constitute the spun yam winding facility 200 of the present embodiment are compacted in a vertical direction.
  • the height of the spun yam winding facility 200 can be compacted in a vertical direction.
  • the workability for the spun yam winding devices 100 which are located on the upper stage is improved.
  • the plurality of spun yam winding devices 100 can be stacked in the up/down direction in multiple stages in a state of a longitudinal layout. As such, the space is effectively utilized.
  • a spun yam winding facility 300 of the present embodiment is composed of the combination of the plurality of spun yarn winding devices 100 which are described in Embodiment 1 wherein some of which are located on the upper stage and others of which are located on the lower stage. Detailed explanation with regard to the spun yam winding device 100 is omitted.
  • the spun yam winding devices 100 are located on both the upper and lower stages in a state of a horizontal layout.
  • the yarns Y are spun at the spinning device (not shown in Figures) which is disposed at the upper portion and then fed to each spun yarn winding device 100 through the intermediary of the rollers 52, 54, 56 etc.
  • the running direction of the yarns Y is changed at the roller 56, and then the yarns Y are fed to the traverse device 32 of each spun yam winding device 100 from the side portion.
  • the spun yam winding facility 300 is composed of the combination of more than one spun yam winding devices 100 wherein the spun yam winding devices 100 are located both the upper and lower stages in a state of horizontal layout, and the spun yarn winding facility is configured so that the yarns Y are fed to each of the traverse devices 32 of the spun yam winding devices 100 from the side portion, the horizontal width of the spun yam winding facility 300 becomes widened, and the excess horizontal width causes increase in size of the spun yam winding facility 300 in a horizontal direction. And as the horizontal width of the spun yam winding facility 300 becomes widened, the working space which is necessary between adjacent spun yam winding devices 300 becomes small, and workability for the spun yam winding device 100 becomes deteriorated.
  • the spun yam winding devices 100 which constitute the spun yam winding facility 300 of the present embodiment are compacted in a vertical direction.
  • the spun yam winding facility 300 can be compacted in the horizontal direction.
  • the working space which is necessary between adjacent spun yam winding devices 300 is ensured, and the workability for the spun yam winding devices 100 can be improved.
  • the plurality of spun yam winding devices 100 can be stacked in up/down direction in multiple stages in a state of horizontal layout. As such, the space can be utilized effectively.
  • the spun yam winding device of the present invention is industrially useful because its vertical length can be held down.
  • the spun yarn winding facility composed of the combination of the plurality of spun yam winding devices of the present invention is also industrially useful because the plurality of spun yam winding devices can be vertically stacked in multiple stages without impairing the workability and thereby the space can be utilized effectively.
